Water Outlet Neck B/RB
Also known as a thermostat housing. Better Quality than Original Zinc made housing. Works on most all Big Block applications. Made from solid Aluminum.
Generally, this design does not leak like the Aftermarket Chrome Housing available on the market.
Comes with WP440A Assembly
As all Big Blocks were designed, this housing is machined to accept the thermostat in it, which bolted to a flat surface on the water pump housing. Most LA Small Block Intakes were machined to accept the thermostat and then use a flat Thermostat Housing.
